POWER-DRIVE POR canoni]iivcfiv'iiiciiiiiiis.y

To all whom t mag/concern y f l 'f Be it known that I, `FREDERICK Gr.JAHN, a citizen of the UnitedStates, andvv resident of Brooklyn, in thecounty of'Kings and State of New York, have inventedcertain new anduseful Improvements in Power-Drives for CancelingeMachines, of whichthefollowing is` a specification.

Thisinvention relates to canceling inachines. The ordinary cancelingmachine `in use, operates upon the'planof `feeding let` ters, checks,cards, or the like, from loose groups or packages held iny thel right.-hand, standing vertically on edge,- the `feeding mechanism snatchingthe cards or sheetsfoff the group individually with great rapidity,- andnafairly uniform procession or series, although the uniformity fisnot byany means absolute in the sensethat'there is]v anv even spacebetweenvthe sheets Orfcards fed in such--` procession. These machines; areoper-k ated bypower wherever electricity is avail-y able, but obviouslysince the demands of the'.

machine can not waitfor a supply of` ower during periods -thatthe sameis cut o it is] necessary to have a hand operation ofthe machine.Thus'the machines are preferably constructed with both hand operatingmeans and power Operating means, and the same must necessarily `bequickly changed y fromv one to the other.

In my prior United States Patentv No. 856,845 a canceling machine isillustrated having these general standard features of construction,'such as a hand wheelfon an inclined axis adapted to be spun by the lefthand while a package of letters isbeingheld l against the feeding`wheels by the right hand. vThis patent also illustratesy the'general`character of the feeding wheel, andthe train of gearing by, which allthe rotating parts yare interconnected. It will ybe ob-y served that alarge number of gearsare used, and it is practically importantvthatthesegearsbe all immersed in an oil pan, and y that the oil pan lbelwithout any 'such openf ings or bearings extending through its Wallsasmight let the Oil. escape after Sachbear-v ings had become worn. Alsoit will be observed that'the feeding disksare necessarily fSpecification of Letters Patent i ,y Patented N0V 3 1914. i Applicationmed October 23, 1912. serial iro. 727,382. i f

located quite close to the surface of the table since checksand lettersaref of a spe-` cial heightwhich will not bey changed, so i that theycharacter of themacliine must besuited to this work. #In other words,the

more than half the height of the average 'mailymatter or bank note.These various conditions, which must be practically complied witli, havemade it amatt'er of great difficulty to drive thefmachine by power.`

Constructions 'embodying the invention will vof course include the usuallarge feed rubber l, and the usual small feed rubber 2, as these feedingwheels are termed in the art, and which arei'apidly rotating frictiondisks on vertical axes slightly elevated above the surface of thecanceling table. yThe small feed rubber has an upwardly extendsoy inghub 3, which is smoothly polished, and

whose'purpose is to furnish a sort of a support for the `upper portionsof a group of letters or the like being pressed over toward this roll bythe right hand. Both of these `rollers are positively driven 'and areintergeared by gears 5 below the table which are iminersedwin the oilpan under the table which is shown, for example, in my' prior patentlabove referredto. The usual hand "drive is likewise*illustrated Linthis "prior patent, andthese' features 'arev not changed by thek presentinifcntion and' are' therefore not shown.

As'ameans of power operation however,

the small feed rubber 2 is positively driven by a connection above thetable and below the frictional periphery ofthe roll, and

of the matter to be canceled, and which isl guided in bearings 8 so asto mesh with a worm gear 9 on the shaft 10 carrying the l small feedrubber 2. The horizontally eX tending spindle will of course rotate at ahigh rate of speed, and is only well adapted to be driven at such aspeedby a direct drive or through a belt from a high speed power source.Asisknown a belt driven by an electric motor is capable of transmittingrotation at a very high speed, without fthe objectional wear and noisethat would be present with gears or the like. By having this spindlerotate at very high speed, the small feed rubber 2 can also be rotatedat fairly high speed notwithstanding a reduction of speed fromthe wormto gear drive. Furthermore the use of the'worm in this way permits theuse of a power means which is completely beneath the level of the smallfeed rubber 2 and scarcely takes up any more vertical height than thethickness of the worm gear itself. On Athe other hand this mechanismdoes not project either into or under the table where it would interferewith the oil pan, or beyond the small feed rubber into the path of thematter to be canceled. In other words, the yworm gear and the worm aresubstantially vcovered by the feed rubber, not projecting beyond theperiphery of the same intothe path of the mail matter, nor to eitherside to such an extent as to be an obstruction to the free movement ofthe hand of the operator. The mechanism furthermore does not projectlaterally so as to 'interfere with the large feed rubber. Thus all theconditions mentioned in the preliminary part of the specification areobtained, and a power drive is provided which can be used wheneverdesired c'. whenever a power source is available.

IWhen the hand power drive for the machine is used, the worm drive mustof course be disconnected for obvious reasons, andfor this reason thebest practical construction embodies a tube or sleeve 12, carrying thetwo bearings or journals 8 for the worm spindle. This tube or sleeve isreceived in a split yoke or frame 18 having a. screw 14, by which thesame can be tightened on the tube or sleeve to hold the same in anyposition. When the canceling machineV is worked by hand the set screw14: is loosened and the tube or sleeve `12 pulled out so as 65 towithdraw the worm from the worm gear, after which the machine isentirely free to operate without being hampered at all by the powerconnection.. y i j They worm, the worm vspindle and the worm gear, areall cased in a suitable housing 15 secured tothe surface of the'tablewhich permits theparts to be lubricated, withoutex'posing the matter tobe canceled tolubricant on the one hand, and protecting the parts fromgrit and dust from the canceledk matter'on .the other hand. The housingis compactly built around the worm geark and the worm, so that theentire housing is substantially located beneath the feed rubber, exceptfor the 'worm shaft extension in one direction. Thus the device neitherinterferes with the movement of the articles to becancelechnor the handsof the operator.

What is claimed is c 85 1. In a canceling machine, a vertically eX-tending shaft, a` feed rubber fixed tofsaid shaft, a horizontal table onwhich the matter to be-canceled stands when pressed against vthe feedrubber, a worm gear for the feed rubber below the 'feed rubber andsubstantiallyv covered thereby and above the table, anda spindle havinga worm extending along the upper surface of the table-and meshing withsaid worm gear, said spindle extending from one side of said worm andsaidworm being out of the pat-h of the matter to be canceled. y I lf2.In a canceling machine, a vertically eX- tending shaft, a feed rubberfixed to said shaft, a horizontal table on which the matter to `becanceled stands when pressed against the feed rubber, a worm gear forthe feed rubber below the feed rubber and above the' table, a wormmeshing with said worm gear, a spindle extending from the side of theworm along the upper surface of the table, and a housing substantiallylocated beneath the feed rubber and covering the worm spindle the wormand the worm gear to prevent the lubricant thereon from reaching themail matter and the dust from the mail matter from reaching the saidparts.

3. In a canceling machine, a feed rubber, a table on which the matter tobe canceled stands when pressed against the feed rubber, a worm gear forthe feed rubber below the feed rubber and above the table, a spindlehaving a worm extending along the upper surface ofthe table and meshingwith said worm gear, and meanskfor adjustably locating said wormyspindle in different longitudinal positions whereby the drive can bedisconnected.
